Serine hydroxymethyltransferase

Index Serine hydroxymethyltransferase

Serine hydroxymethyltransferase (SHMT) is a Pyridoxal phosphate (PLP) (Vitamin B6) dependent enzyme which plays an important role in cellular one-carbon pathways by catalyzing the reversible, simultaneous conversions of L-serine to glycine and tetrahydrofolate (THF) to 5,10-methylenetetrahydrofolate (5,10-CH2-THF).
